While riveting and bonding are fine methods for fastening aluminium so is
welding. I've made hundreds of Al welds over the years that neither cracked
or failed because they were "weak". The weld design and procedure does need
to be correct... which any good welding shop should be able to do.

Does your remark include repairs on a welded, multichine hull, of 6, 8
and 12 mm AlMg 4,5 Mn ? If so what wouldin your opinion be the best
way to repair say a hole of 10" diameter ?
I'm told TIG welding is perfectly suited for these kinds of repairs
and would not leave weakened areas behind. Am I being lied to ?

As a matter of fact I'm thinking of take a TIG welding course and take
a rel small welding machine with me.
Am I overlooking other methods ?

Len.

Don't weld. Use stainless pop rivits or bolts. Welding will weaken the
